Naff Movie into 'DVD Spectra'

Step 4Cutting the wedge parts

Cutting the wedge parts
Take your 'wedge' template and lay it over the card. I used paperclips to keep it in position while I cut around the outlines using a sharp knife and a metal rule.

The template is such that in general you want to be cutting to the inside of the line. The shaded areas should also be removed. Those top and bottom of the larger endpiece allow the card to sit over the various bits of plastic of the case. Cut these to fit your particular case, but leave enough left and right to steady the card fit.

You will want to lightly score the indicated horizontal line. This is the line you will align your spectrometer slit with.
